TMS320F28P650DH: C2000_Ware EMIF demo issue

Hi experts

I'm encountering an issue with the EMIF interface. When using the emif_ex1_16bit_asram example from C2000Ware, I noticed that the ASRAM_CS2_START_ADDR is defined as 0x10 0000, whereas the hardware manual specifies that the starting address for CS2 should be 0x30 0000. Additionally, 0x10 0000 is the starting address for FLASH_BANK4. Why is this discrepancy occurring?

In debug mode, when I attempt to write to address 0x30 0000, I receive an error, and the device remains in a reset state. Could you help me understand the root cause and how to resolve this issue?

Hi Ethan,

Let me check with our design team on this because both our software headers and memory map documentation should be coming from the same source. This could be either a literature bug or a software bug, I will let you know

Regards,

Peter

Hi Ethan,

Following up with this, the original memory address configured as 0x10 0000 works for you in the example before you make any alterations?

Peter

Hi Peter

I just don't know why it was configured as 0x10 0000, I can't find any references in TRM

Hi Ethan,

I believe this is a literature bug but I am still confirming with design
